🎀 gmc_v7_0_flush_gpu_tlb_pasid 🎀

✨ NAME ✨

gmc_v7_0_flush_gpu_tlb_pasid — tlb flush via pasid 🌸

like, that's the whole vibe. she flushes a TLB. via a pasid. that's the tweet.

🦋 SYNOPSIS 🦋

void gmc_v7_0_flush_gpu_tlb_pasid (struct amdgpu_device *adev , uint16_t
pasid , uint32_t flush_type , bool all_hub , uint32_t inst );

returns void, so she gives you nothing back — no return value, no little gift, just vibes and a freshly flushed TLB ✨ and yes, no cap, that's the exact signature, don't come for me 🫶

💖 ARGUMENTS 💖

  • adev — amdgpu_device pointer. your main character — the device struct everything runs through 👑
  • pasid — pasid to be flush. yes, the manpage says "flush", we're keeping it, it's iconic 💀 this is the pasid you're targeting.
  • flush_type — type of flush. the type. of the flush. extremely important, extremely unspecified, love that for us 🙈
  • all_hub — flush all hubs. set it and she goes wide, flushing every hub 💫
  • inst — is used to select which instance of KIQ to use for the invalidation. so like, which KIQ gets the job, iykyk 🧚

🔥 DESCRIPTION 🔥

Flush the TLB for the requested pasid.

that's it. that's the whole thing. one (1) sentence of pure purpose 😭 honestly obsessed with the confidence — no extra lore, no filler, just flush the TLB for the requested pasid, periodt 💅
